state-of-the-art dilution refrigerators with fast sample exchange Top

Crucial criterion for certain experiments such as scanning probe microscopy is the ability
for fast turnaround times for tip and sample exchange. This is possible by using fast sample
exchange mechanisms, which are available either the so-called top-loaders, or bottom-loaders
(see schematics on the right).
Through close collaborations with DR suppliers and leading scientists in several projects over the
last 20 years, attocube has gained substantial experience in helping to choose appropriate DRs,
providing the right components enabling special applications, and assiting with their integrati-
on into the mK environment.

While top-loaders provide slightly higher cooling power, bottom-loaders carry the advantage of
significantly lower overall system size, making them the right choice in case of limited ceiling
height in existing laboratories. In addition, the cabling in bottom-loaders is routed through
the main DR itself, which helps to thermalize the wiring.
DR with top-loading probe
Top-loading probes constitue the standard soluti-
on for fast sample exchange in DRs, which enables
both fast turnaround time for sample exchange
and high cooling power.

Fast sample exchange via bottom-loading probes
further increases the ease-of-use, and significantly
decreases the required room height for installation
of a DR.
